B-Line Eaton series wall mounted panel enclosure, 48" height, 16" length, 36" width, 4X, Hinged cover, 4XSS63PT enclosure, Wall mount, Medium single

That's what the 4X rating is for. The 483616-4XSS63PT is built from 316 stainless steel with a NEMA 4X rating, so it handles hose-directed water and corrosive environments, food and beverage washdown, coastal salt air, and chemical areas. 316 is the higher-molybdenum stainless grade, which is why it is specified over 304 where chlorides are present. The door seals against a seamless poured in-place gasket rather than a cut-and-glued gasket, so there is no joint in the seal to fail.

146.3 pounds empty, before any panel, breakers, or drives go in. That is a two-person lift and it needs structural backing, not drywall anchors. The 483616-4XSS63PT mounts by external mounting feet, so the fasteners land outside the sealed body and you never breach the enclosure to hang it, which is the point on a 4X install. Land the feet on studs, unistrut, or a steel stand rated for the loaded weight.

Yes. The 4XSS63PT enclosure carries UL 508A, the standard for industrial control panels, so it is the right shell if you are building a listed control panel and need the enclosure to support that listing. Verify your internal component selection and short circuit current rating separately, since those are part of the panel build, not the box.

Single door, hinged, in the medium single door style. One 36 inch wide leaf swings on a continuous hinge and latches with the 3-point handle. If your layout needs two narrower leaves for a tight aisle where a 36 inch door swing will not clear, a single-door box of this width is the wrong choice and you want a double door enclosure instead.

The description covers the enclosure itself: 48 x 36 x 16 body, hinged medium single door, 3-point latching handle, external mounting feet, 316 stainless, poured in-place gasket. Order your back panel, DIN rail, terminal blocks, and any window or cooling kit separately, and plan any conduit hubs as 4X rated fittings so you do not compromise the rating when you penetrate the box.

Yes, it has key lock and padlock provision. The 3-point latching handle pulls the door tight at three points along the latch side, which is what keeps a 48 inch tall door sealed evenly against the gasket, and the handle accepts a padlock for lockout or site security.

14 gauge throughout. That is the standard body gauge for wall mount industrial enclosures of this size and it carries a loaded panel without the door or sides flexing away from the gasket line. Combined with the 316 stainless material and 4X rating, it is an outdoor and washdown grade box rather than an indoor-only 12 style enclosure.

It is a #4 brushed stainless finish, the same directional satin grain used on food-grade tables, sinks, and process equipment, so it reads consistent alongside other stainless gear. There is no paint to chip or chalk, which matters in a sanitized area where painted steel eventually blisters at the seams.

Country of origin is US on the 4XSS63PT enclosure. For a federal or state procurement with domestic sourcing language, pair that with the UL 508A listing when you submit the enclosure on the spec.
